• Converting a JD Edwards Date to a System.DateTime

  - by Christopher House

  I'm working on moving some data from JD Edwards to a SQL Server database using SSIS and needed to deal with the way in which JDE stores dates.  The format is CYYDDD, where: C = century, 1 for >= 2000 and 0 for < 2000 YY = the last two digits of the year DDD = the number of the day.  Jan 1 = 1, Dec. 31 = 365 (or 366 in a leap year) The .Net base class library has lots of good support for handling dates, but nothing as specific as the JD Edwards format, so I needed to write a bit of code to translate the JDE format to System.DateTime.  The function is below: public static DateTime FromJdeDate(double jdeDate) {   DateTime convertedDate = DateTime.MinValue;   if (jdeDate >= 30001 && jdeDate <= 200000)   {     short yearValue = (short)(jdeDate / 1000d + 1900d);     short dayValue = (short)((jdeDate % 1000) - 1);     convertedDate = DateTime.Parse("01/01/" + yearValue.ToString()).AddDays(dayValue);   }   else   {     throw new ArgumentException("The value provided does not represent a valid JDE date", "jdeDate");   }   return convertedDate; }  I'd love to take credit for this myself, but this is an adaptation of a TSQL UDF that I got from another consultant at the client site.

• PHP: gethostbyname() suddenly no longer resolves names to IPs when run in Apache

  - by hurikhan77

  One of our older legacy servers which gets no further updates or reconfigurations suddenly stopped resolving hostnames to IPs when PHP is executed within Apache. However, it still works fine when executed from the CLI. From the RSS caches last modification time, I deduce that it stopped working on around Mar, 28th. To reproduce the problem, I created a script using fsockopen() and it said "connection failed (errno 2)". I further reduced the problem to being related with a failed name resolution: <?php $addr = gethostbyname("twitter.com"); echo "ADDR($addr)"; ?> When I run this through Apache, the output is ADDR(twitter.com), which is wrong. When I run this from the CLI, the output is ADDR(aaa.bbb.ccc.ddd) with varying IP addresses, as expected. Nothing on the server setup has changed. CLI and Apache module share the same php.ini. PHP is version v4.4.9 with Zend Optimizer v2.5.10. Apache is v1.3.31. I know the versions are old. But since nothing has been changed, a solution like "try to upgrade versions first" is no solution as the server's feature set/versioning is frozen and will be replaced soon. Still we need a solution. If I run dig through the script, it works in both environments (mod_php and CLI) but this is more than an ugly hack as it would involve many edits and testing throughout the whole script base which is also undesired as the PHP application on the server is frozen, too, and only receives security updates. It will be replaced by a complete rewrite (on the new server). But as the rewrite will take some time and successive replace parts of the legacy application, we need a fix for the resolver problem. I already googled a bit and while the problem is known, many did not find a fix. The fix to raise memory limits did not work. Restarts did not work. The resolver in mod_php just did stop working for no apparent reason. :-(

• What does the -P option do to mount?

  - by Simon

  I'm migrating from an archaic version of Red Hat to Ubuntu 9. When going through my old nfs mount script, I found that it contained the -P option. So my script looks like: sudo mount -t nfs -o -P ... It looks like the -P is one of the -o options. My question is: what does the -P option do? I've searched every man page I can find, with no luck. Could it have to do with privileged ports?

• SQL SERVER – How to Change Compatibility of Database to SQL Server 2014

  - by Pinal Dave

  Yesterday I wrote about how we can install SQL Server 2014. Right after the blog post was live, I received a question from the developer that he has installed SQL Server 2014 and attached a database file from previous version of SQL Server. Right after attaching database, he was not able to work with the latest features of Cardinality Estimation. As soon as he sent me email I realize what has happened exactly. When he attached database, the database compatibility was set to still of the earlier version of SQL Server. To use most of the latest features of SQL Server 2014, one has to change the compatibility level of the database to the latest version (i.e. 120). Here are two different ways how we can change the compatibility of database to SQL Server 2014′s version. 1) Using Management Studio For this method first to go database and right click over it. Now select properties. On this screen user can change the compatibility level to 120. 2) Using T-SQL Script. You can execute following script and change the compatibility settings to 120. USE [master] GO ALTER DATABASE [AdventureWorks2012] SET COMPATIBILITY_LEVEL = 120 GO   Well, it is that easy :-) Reference: Pinal Dave (http://blog.SQLAuthority.com)Filed under: PostADay, SQL, SQL Authority, SQL Query, SQL Server, SQL Tips and Tricks, T SQL

• Jenkins swarm-plugin jar file, won't run in background

  - by JeanMertz

  We're working on an automation script for our Jenkins slaves on a local Unix server. To connect the slaves to the Jenkins master, we use the swarm plugin. Setting up the master was easy, and connecting clients is also easy with a single command. However, I am trying to get the slave command (a java application) to run in the background without stalling the current process, this doesn't seem to work. I've created an init.d file and added it to update-rc.d but that doesn't work. #!/bin/bash /usr/bin/java -jar /root/swarm-client-1.7-jar-with-dependencies.jar -executors 4 I've also tried to run it with an ampersand & to start the process in the background, but that doesn't work either because - from looking at the source - the jar file actually boots another process that is then started in the foreground. Any ideas on how to make this jar file start without stopping the bootstrap script?

• Performance Alert Writing to event Log but not running program

  - by TooFat

  I followed the instructions here How to create and configure performance alerts in Windows Server 2003 to set up an alert if the available logical disk space on one of my drives goes below a certain number. I selected the option to write to the application event log and select the "run this program" option and put in the path to a script that sends me an email. If I copy the path to the script and run it everything works and I get the email. When I start the alert I can see that the limit I set is being exceeded and the logs are being written to the application log, but the email is never being sent. I have the runas user and pword set to a Domain Admin. If I make the "run this program path" to C:\Windows\System32\calc.exe" it also doesn't start up the calculator. The Performance Logs and alerts services is running as Local Admin with allow to interact with desktop. What am I doing wrong?

• Need help generating a core dump from apache segfault

  - by blockhead

  I have a script which intermittently returns a white screen of death in firefox and Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error. chrome. When I try to access the script using a PHP HTTP client (like Zend_Http_Client), intermittently I get an exception (sorry I don't have the exact message on me at the moment). I suspect a segfault. This is further buttressed by the lines in my error log that look like this: [Thu Mar 18 16:03:02 2010] [notice] child pid 845 exit signal Segmentation fault (11) Now, I'm running RedHat, and I know that RedHat doesn't generate core dumps out-of-the-box. I followed the instructions here http://kbase.redhat.com/faq/docs/DOC-5353, but I'm not seeing any core dumps. How do I generate a core dump?

• How to execute with /bin/false shell

  - by Amar

  I am trying to setup per-user fastcgi scripts that will run each on a different port and with a different user. Here is example of my script: #!/bin/bash BIND=127.0.0.1:9001 USER=user PHP_FCGI_CHILDREN=2 PHP_FCGI_MAX_REQUESTS=10000 etc... However, if I add user with /bin/false (which I want, since this is about to be something like shared hosting and I don't want users to have shell access), the script is run under 1001, 1002 'user' which, as my Google searches showed, might be a security hole. My question is: Is it possible to allow user(s) to execute shell scripts but disable them so they cannot log in via SSH?

• Bash delete file when variable = x

  - by twigg

  I'm creating a bash script which reboots the system at each reboot it adds a new line to a text file, I then read the text file before each reboot. Once the variable holding the number of lines reaches say 10 I want the script to delete the text file (at which point on the next reboot it will see the file isn't there, brake the loop and promote the user to start again). I tried this: exec < text.txt nol=0 while read line do nol=`expr $nol + 1` done reboot_count=10 if ["$nol" == "$reboot_count"]; then rm text.txt fi but this doesn't seem to be working, all help is appreciated :)

• Scripting a database copy from MS Sql 2005 to 2008 without detach/backup/RDP

  - by James Santiago

  My goal is to move a single SQL 2005 database to a seperate 2008 server. The issue is my level of access to both servers. On each I can only access the database and nothing else. I cant create a backup file or detach the database because I don't have access to the file system or to create a proxy. I've tried using the generate script function of sql 2005 management studio express to restore the schema but receive command not supported errors when attempting to execute the sql on the new database. Similarly I tried using EMS SQL Manager 2005 Lite to script a backup of the schema and data but ran into similar problems. How do I go about acomplishing this? I can't seem to find any solutions outside of using the detach and backup functions.

• syslogd: Logfile format (not configuration format)

  - by chris_l

  Hi, I'd like to parse logfiles. Is the logfile format of syslogd the same for all systems? On my system (Debian Lenny), it's: Mar 7 04:22:40 my-host-name ... (I'm not much interested in the ... part) Can I rely on this? And is there maybe some more-or-less official description? The manpage of syslogd describes the config format, but not the logfile format. Ideally, the description would give the fields official names like (date, time, host, entry) or (datetime, hostname, message). Maybe additionally some regular expressions. I'd like to use the names and regexes in my script, to avoid an unnecessary deviation from the standard, and to make sure, that the script runs everywhere. Thanks Chris

• Booting from USB on Mac Air (using setup_mac_usb_boot.sh)

  - by Mike O

  So, I've been working on this for hours and it's getting a little tiring. As some of you may know, installing Ubuntu on Macs is frequently an adventure, and I'm experiencing that right now. The part I'm hung up on at the moment is making a bootable USB. I would just use a CD, but my laptop is a MacBook Air (which doesn't have a CD drive), and I don't own an external CD drive. I initially attempted to use the command line method supplied by the Ubuntu documentation here: https://help.ubuntu.com/community/How%20to%20install%20Ubuntu%20on%20MacBook%20using%20USB%20Stick However, that wasn't even recognized by rEFIt even when I made a number of different modifications to the process, so I quickly decided to look elsewhere. I came across this guide: https://help.ubuntu.com/community/MacBookAir4-2#Basic_Installation_Instructions This ended up working to a large extent. If I choose the supplied grub from rEFIt, it will bring me to the Ubuntu grub, asking me to try it, install, or check the disk. And if I choose to boot Linux directly from rEFIt, it will bring me to the language selection menu. But when I make my selection from either of these menus it pauses for about ten seconds and then gives me a command line error message. It begins with kernel panic - not syncing timer doesn't work through interrupt, and then shows about eight file names. Does anyone here have any ideas as to what can be causing this? I also tried the script with both Ubuntu 11.10 (the current version when the script was written) and 12.04.

• How to Create a Minimize All Windows (Win + M) Hotkey for Mac OS X

  - by The Geek

  Windows users have been able to minimize every window on their desktop ever since keyboards with the Win key started showing up — just tap WIN + M on your keyboard, and every window is minimized. For Mac OS X, it’s not quite as simple. You can, of course, use the CMD + OPT + H + M shortcut key combination to hide most windows… but that’s a lot of keys to hit at once, and it doesn’t always minimize everything in my experience. So like everything else I wanted from Windows, it was time to figure out how to get it on OS X as well. This method uses QuickSilver to provide the shortcut key trigger — if there’s a better way to do that, please let us know. Luckily OS X includes a nice scripting platform, and we can use the following script from a helpful person over at SuperUser to make this all happen. tell application "Finder" to activate tell application "System Events" tell application process "Finder" tell menu bar 1 click menu item "Hide Others" of menu of menu bar item "Finder" click menu item "Minimize All" of menu of menu bar item "Window" end tell end tell end tell Open up a new AppleScript Editor window and paste in the script from above. Then go to File and Save.

• Glusterfs : 'No route to host' for fstab mount in CentOS

  - by son_of_fire

  I am using glusterfs, and am using fstab in this way: <IPADDRESS>:/<VOLUMENAME> /some/mount/point glusterfs defaults,_netdev 0 0 but the logs for the mount continue to say the following. [<TIMESTAMP>] E [socket.c:2161:socket_connect_finish] 0-<VOLUMENAME>-client-1: connection to <IPADDRESS>:24007 failed (No route to host) I know this is not true, since when the system is up and running, I can easily issue a mount and the volume gets mounted. (I've done this by using rc.local) after reading more I have seen that using _netdev is preferred, and that if the host cannot be reached netfs will remount the volume after the network comes up, but that is not happening. (netfs is running). Is there a way to make the mount happen at a different time without using a script? (I would prefer to use fstab to manage the mounting even though I can use a script.)

• Lingering tcp connection in LISTEN state

  - by Silvio Donnini

  My java application can sometimes be killed by an external script. This can be done either with SIGTERM or with SIGKILL. The application is a server which receives many connections per second, and it can be killed while trying to serve them. I would like to restart the application whenever it's killed, so I have prepared a script for that purpose. The problem is that, once the app has been killed, the new application instance can't bind to the port used by the previous instance, because the "Address is already in use". The previous instance's process has been definitely terminated, anyway the offending listening port is still there, but it is assigned to bash (or sh on other machines). Obviouly, my goal is to restart the application and let it bind successfully to the previous address. I've tried waiting more than 200 seconds before restarting to no avail, anyway I can't afford to wait that much. I've encountered this problem on all the machines I've ran the application (which is a jetty server with java 1.6). Any suggestion is appreciated, thanks, Silvio

• How should I work out VAT (UK tax) in my eCommerce site?

  - by Leonard Challis

  We have an ecommerce system in place. The sales actually go through Sage, so we have an export script from our system that uses a third-party Sage Importer program. With a new version of this importer, values are checked more thoroughly. We are getting 1 pence discrepancies because of the way rounding works - our system has always held prices and worked to 4 decimal places. In the checkout the totals would be worked out first, then the rounding to 2 decimal places. The importer does rounding first, though. So, for instance: Our way: Product 1: £13.4561 Qty: 2 Total inc VAT = £32.29 (to 2dp) Importer way: Our way: Product 1: £13.4561 Qty: 2 Total inc VAT = £32.30 (to 2dp) Management are reluctant to lose the 4dp but the developers of the Sage importer have said that this is correct and makes sense -- you woudn't sell a product for £13.4561 in a shop, nor would you charge someone tax at 4 decimal places. I contacted the HMRC and the operator didn't really give me much to go on, telling me a technician would phone back, to which they haven't and I'm still waiting after almost a week and numerous follow-up calls. I did find a PDF on the HMRC's web site, but this did about us much to confuse me as it did to answer my questions. I see that they're happy for people to round up or down, as long it is consistent, but I can't tell whether it should be done on a line by line basis or on the end total of the order. We are now in the position where we need to decide whether it's worth us doing one of the following, or something completely different. Please advise with any experience or information I can read. Change all products on the site to use 2dp Keep 4dp but round each line in the order to 2dp before working out tax Keep it as it is and "fudge" the values at the export script (i.e. make that values correct by adding or subtracting 1p and changing the shipping cost to make the totals still work out) Any thoughts?

• How can I install Insight debugger?

  - by DandyWalker

  Hello. I am following along a book in which Insight debugger is required. I didn't find it on my Maverick. I googled and I found that it's not supported in debian anymore but I really need to install it. I tried to compile the source and it installed but keep telling me that tk is missing whenever i start it. I installed tk with sudo aptitude install tk then tried to run again it's the same. I compiled it one more time and nothing really changes. So please how can I install that ? Update: This is the message i get Tk_Init failed: Can't find a usable tk.tcl in the following directories: /usr/local/share/tk8.4 /usr/local/lib/tk8.4 /usr/lib/tk8.4 /usr/local/library /usr/library /usr/tk8.4.1/library /tk8.4.1/library /usr/local/share/tk8.4/tk.tcl: no event type or button # or keysym no event type or button # or keysym while executing "bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D / 120) * 4}] units }" (file "/usr/local/share/tk8.4/listbox.tcl" line 182) invoked from within "source /usr/local/share/tk8.4/listbox.tcl" (in namespace eval "::" script line 1) invoked from within "namespace eval :: [list source [file join $::tk_library $file.tcl]]" (procedure "SourceLibFile" line 2) invoked from within "SourceLibFile listbox" (in namespace eval "::tk" script line 4) invoked from within "namespace eval ::tk { SourceLibFile button SourceLibFile entry SourceLibFile listbox SourceLibFile menu SourceLibFile panedwindow SourceLibFile ..." invoked from within "if {$::tk_library ne ""} { if {[string equal $tcl_platform(platform) "macintosh"]} { proc ::tk::SourceLibFile {file} { if {[catch { namesp..."

  When I use df -h, I get the following output: Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 59G 2.2G 54G 4% / /dev/sda1 122M 38M 78M 33% /boot tmpfs 1.1G 0 1.1G 0% /dev/shm 10.10.0.105:/somepath 11T 8.4T 2.1T 81% /storage4 10.11.0.101:/somepath 15T 8.9T 5.9T 61% /storage1 /dev/mapper/patha 5.0T 255G 4.8T 5% /storage5_vol0 /dev/mapper/pathb 5.0T 195G 4.9T 4% /storage5_vol1 /dev/mapper/pathc 5.0T 608G 4.5T 12% /storage5_vol2 I want to write a script that gets the value of Avail column on a specific storage. I used to use df -k /storage_name | tail -1 | awk '{print $3}' But the FileSystem column can have a value or not .. which would change the variable of my script from $3 to $4. How can I get the Avail on a single command line even if there are no values on the previous columns?

• Implementing dry-run in bash scripts

  - by Apikot

  How would one implement a dry-run option in a bash script? I can think of either wrapping every single command in an if and echoing out the command instead of running it if the script is running with dry-run. Another way would be to define a function and then passing each command call through that function. Something like: function _run () { if [[ "$DRY_RUN" ]]; then echo $@ else $@ fi } _run mv /tmp/file /tmp/file2 DRY_RUN=true _run mv /tmp/file /tmp/file2 Is this just wrong and there is a much better way of doing it?

• In Joomla In htaccess REQUEST_URI is always returning index.php instead of SEF URL

  - by Saumil

  I have installed joomsef version 3.9.9 with the Joomla 1.5.25. Now I want to set https for some of the section of my site(e.g URI starts with /events/) while wanting rest of all urls on http.I am setting rules in .htaccess file but not getting output as expected. I am checking REQUEST_URI of the SEF urls but always getting index.php as URI. Here is my htaccess code. ########## Begin - Custom redirects # # If you need to redirect some pages, or set a canonical non-www to # www redirect (or vice versa), place that code here. Ensure those # redirects use the correct RewriteRule syntax and the [R=301,L] flags. # ########## End - Custom redirects # Uncomment following line if your webserver's URL # is not directly related to physical file paths. # Update Your Joomla! Directory (just / for root) # RewriteBase / ########## Begin - Joomla! core SEF Section # RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] # # If the requested path and file is not /index.php and the request # has not already been internally rewritten to the index.php script RewriteCond %{REQUEST_URI} !^/index\.php # and the request is for root, or for an extensionless URL, or the # requested URL ends with one of the listed extensions RewriteCond %{REQUEST_URI} (/[^.]*|\.(php|html?|feed|pdf|raw))$ [NC] # and the requested path and file doesn't directly match a physical file RewriteCond %{REQUEST_FILENAME} !-f # and the requested path and file doesn't directly match a physical folder RewriteCond %{REQUEST_FILENAME} !-d # internally rewrite the request to the index.php script RewriteRule .* index.php [L] # ########## End - Joomla! core SEF Section # Here is my code e.g site url is http://mydomain.com/events RewriteCond %{REQUEST_URI} ^/(events)$ RewriteCond %{HTTPS} !ON RewriteRule (.*) https://%{REQUEST_HOST}%{REQUEST_URI}/$1 [L,R=301] I am not getting why REQUEST_URI is reffering index.php even though my url in address bar is like this http://mydomain.com/events . I am using JOOMSEF(Joomla extension for SEF URLS).If I am removing other rules from the htaccess file then joomla stops working. I am not getting a way to handle this as I am not expert.Please let me know if someone has passed through same situation and have solution or suggest some work around. Thanks

• Windows Azure Database (SQL Azure) Development Tip

  - by BuckWoody

  When you create something in the cloud, it's real, and you're charged for it. There are free offerings, and you even get free resources with your Microsoft Developer Network (MSDN) subscription, but there are limits within those. Creating a 1 GB database - even with nothing in it - is a 1 GB Database. If you create it, drop it, and create it again 2 minutes later, that's 2 GB of space you've used for the month. Wait - how do I develop in this kind of situation? With Windows Azure, you can simply install the free Software Development Kit (SDK) and develop your entire application for free - you need never even log in to Windows Azure to code. Once you're done, you simply deploy the app and you start making money from the application as you're paying for it. Windows Azure Databases (The Artist Formerly Known As SQL Azure) is a bit different. It's not emulated in the SDK - because it doesn't have to be. It's just SQL Server, with some differences in feature set. To develop in this environment, you can use SQL Server, any edition. Be aware of the feature differences, of course, but just develop away - even in the free "Express" or LocalDB flavors - and then right-click in SQL Server Management Studio to script objects. Script the database, but change the "Advanced" selection to the Engine Type of "SQL Azure". Bing. Although most all T-SQL ports directly, one thing to keep in mind is that you need a Clustered Index on every table. Often the Primary Key (PK) is a good choice for that.

• Securely wiping a file on a tmpfs

  - by Nanzikambe

  I have a script that decrypts some data to a tmpfs, the directory is secure (permissions), the machine's swap is encrypted (random key on boot) and when the script is done it does a 35 pass wipe (Peter Gutmann) of the cleartext on the tmpfs . I do this because I'm aware wiping files on a journaling file system is insecure, data may be recovered. For discussion, here're the relevant bits extracted: # make the tmpfs mkdir /mnt/tmpfs chmod 0700 /mnt/tmpfs mount -t tmpfs -o size=1M tmpfs /mnt/tmpfs cd /mnt/tmpfs # decrypt the data gpg -o - <crypted_input_file> | \ tar -xjpf - # do processing stuff # wipe contents find . -type f -exec bcwipe -I {} ';' # nuke the tmpfs cd .. umount -f /mnt/tmpfs rm -fR /mnt/tmpfs So, my question, assuming for the moment that nobody is able to read the cleartext in the tmpfs while it exists (I use umask to set cleartext to 0600), is there any way any trace of the cleartext could remain either in memory or on disk after the snippet above completes?
